Brokers cut their full-year profit forecasts by £40million to £50 million today, reducing the consensus from £592 million to around £545 million.
The shares fell 70p, or 6% to 1057p and have dropped 30% since June 23.
The third quarter which included the Brussels attack and EgyptAir crash also saw a near record 1,221 flight cancellations because of air traffic control strikes, runway closures at Gatwick and severe weather.
Revenues dropped 2.6% to £1.2 billion. The final quarter has already seen the attack in Nice, where easyJet is the largest airline, and the attempted coup in Turkey.
“There have been an extraordinary number of external events,” said McCall. “That affects consumer confidence and pricing. Despite this we carried more passengers and had a higher load factor. The pricing environment will wash out because in times like this strong airlines get stronger and weak airlines get weaker.”
She said easyJet had mobilised a team to deal with Brexit and was already talking to ministers and regulators but also had a plan which could see it move its headquarters to secure an EU Airline Operator Certificate.
“We would like things to remain as they are today because that is in the best interests of our customers and of the economy,” she said.
“Our first priority is ensuring, in any way we can, that a liberalised aviation market continues in Europe. EasyJet, IAG and Ryanair, along with other European airlines and European airports, all want that.
“Almost half of our customers don’t touch the UK in any way. So we have to have a contingency plan but we would only activate that out of neccessity not choice.”
